Apparatus for harvesting rainwater
A rainwater collection apparatus is formed with an outer sleeve member that is adapted to connect with upper and lower downspout portions, and with an internal colander that is operable to collect and filter the rainwater flowing through the upper downspout portion. The colander has an upper flanged edge that removes water flowing along the inside surface of the downspout, a filter area including a plurality of apertures for the passage of rainwater into a catch basin, and a support flange that rests on a base ledge formed on the outer sleeve to define the catch basin. A discharge spout drains the collected rainwater from the catch basin to a remote storage container. An internal opening in the colander allows the passage of debris and the overflow of rainwater from the catch basin through apertures in the colander for discharge through the lower downspout portion.
1. A rainwater collection apparatus for mounting to a downspout on a building structure, comprising:
an outer sleeve member attachable to an upper downspout portion and a lower downspout portion, said outer sleeve member including a discharge spout;
a colander member mounted within said outer sleeve member and including a flared upper edge portion, a main body portion and a generally horizontal flange projecting outwardly from said main body portion, said main body portion including an upper filter area and a lower belt area, said colander being smaller in size than said outer sleeve member to define a catch basin therebetween in flow communication with said discharge spout.
2. The rainwater collection apparatus of claim 1 wherein said outer sleeve member is formed with a generally horizontal base ledge on which said flange is supported, said catch basin being defined in width by said flange mounted on said base ledge and in height by said belt area.
3. The rainwater collection apparatus of claim 1 wherein said colander projects vertically above said outer sleeve member such that said flared upper edge portion projects upwardly and outwardly from said main body portion to be positioned proximate to an interior wall surface of said upper downspout portion.
4. The rainwater collection apparatus of claim 3 wherein said filter area includes a plurality of apertures through which rainwater can pass into said catch basin.
5. The rainwater collection apparatus of claim 4 wherein said flared upper edge makes an angular bend from said filter area, said main body portion projecting upwardly and outwardly from said flange to said flared upper edge portion.
6. The rainwater collection apparatus of claim 5 wherein said discharge spout is selectively connectable to a conduit to diverted collected rainwater to a remote storage container or to a cap to force collected rainwater within said catch basin to overflow through said filter area into said lower downspout portion.
7. The rainwater collection apparatus of claim 5 wherein said outer sleeve member is formed with a generally horizontal ridge positioned above said base ledge to provide a stop for the insertion of said upper downspout portion into said outer sleeve member for connection therebetween, said outer sleeve member further having an inner leg projecting downwardly from said base ledge for insertion into said lower downspout portion and connection thereto.
8. The rainwater collection apparatus of claim 5 wherein said catch basin extends circumferentially around said colander member, said base ledge and said ridge extending circumferentially around an interior surface of said outer sleeve member.
9. In a rainwater collection apparatus having an outer sleeve member mountable to upper and lower downspout portions for the collection or rainwater from said upper downspout portion, the improvement comprising:
a colander member supported in said outer sleeve member and including a flared upper edge portion, a main body portion and a lower mounting flange projecting outwardly from said main body portion, said flared upper edge portion being positioned proximate to an interior wall surface of said upper downspout portion to collect rainwater moving along said interior wall surface, said main body portion including an apertured upper filter area and a solid lower belt area between said apertured upper filter area and said lower mounting flange.
10. The rainwater collection apparatus of claim 9 wherein said flared upper edge portion extends upwardly and outwardly from said main body portion and forming a bend therebetween to separate debris from rainwater collected by said flared upper edge portion.
11. The rainwater collection apparatus of claim 10 wherein said main body portion being angled outwardly from said mounting flange to said flared upper edge to provide a sloped filter area over which collected rainwater can flow from said flared upper edge portion.
12. The rainwater collection apparatus of claim 11 wherein said outer sleeve member is formed with a generally horizontal base ledge for the support of said mounting flange.
13. The rainwater collection apparatus of claim 12 wherein said main body portion is spaced inwardly from said outer sleeve member to define a gap therebetween creating a catch basin for receiving collected rainwater passing through said filter area, said catch area having a height corresponding to said belt area and being in flow communication with a discharge spout formed in said outer sleeve member for the diversion of the collected rainwater from said catch basin.
14. The rainwater collection apparatus of claim 13 wherein a lowermost set of apertures in said filter area serves as an overflow for said catch basin for the passage of overflowing rainwater into said lower downspout portion.
